Problems solved by technology

[0003] The main purpose of the present invention is to provide a method, device, device, and computer-readable storage medium for raising the rights of an application program, aiming at solving the problem that the existing method for raising the rights must have an SU file, thus causing a third-party application program to detect the SU file. technical issues that may refuse to provide certain core services due to security risks

Embodiment Construction

[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The current system privilege escalation method is to start a Root process as a client, and provide root services to users through Socket. Since the SU file must exist for privilege escalation, the third-party application can easily determine whether the system provides Root privilege escalation by executing or detecting the SU file. If the SU file is detected, the third-party application may cause security risks. , denying certain core services.

[0037] In order to solve the above problems, the present invention provides a solution, by matching the package name of the target application program with the package name in the preset extraction configuration table after the target application program is started in the system, if the matching is not successful, the target The application performs privilege reducti...

Abstract

The invention discloses an application program privilege extraction method, device and equipment and a computer readable storage medium, and the method comprises the steps of enabling a package name of a target application program to be matched with each package name in a preset privilege extraction configuration table after the target application program in a system is started; if the matching isnot successful, performing weight reduction processing on the target application program; and if the matching succeeds, maintaining the root user permission for the target application program. The defect that the third-party application program can detect whether the system improves the root privilege or not through the SU file is overcome.

Description

technical field [0001] The present invention relates to the technical field of system security, in particular to a method, device, equipment, and computer-readable storage medium for elevating application privileges. Background technique [0002] Existing method of escalating rights is realized by an executable file called SU (Switch user, switch user). The entire implementation is divided into two parts, namely the server and the client. The server is root (super user) process, start SU through init. The root user on the server side provides services for ordinary users on the client side. Disadvantages of the existing root privilege escalation method: since the SU file must exist for privilege escalation, third-party applications can easily determine whether the system provides Root privilege escalation by executing or detecting the SU file. If the SU file is detected, the first Third-party applications may refuse to provide certain core services due to security risks. ...
